If you suddenly loose HD Presets or can no longer Import, or work with any form of MPEG Assets, it is likely that your full-paid version of PrPro has been bitten with the "Revert to Trail Bug." This has happened to several users, and is most often the result of updating PrPro. As a quick check, create a New Sequence, and see if you still have all of the HD Presets. It is likely that you do not. This affects anything MPEG, whether HD, or SD, and that is just to quickly see what you have available. Existing Projects might start throwing Media Offline messages, and one will get "Unsupported file formats," when they try to Import MPEG files.

The "fix" is a multi-step operation, and in this order:

Deactivate, if possible (probably not, as the trial is not Activated)

Uninstall PrPro

Download and run the Adobe Cleaner Tool(latest version) several times, rebooting between each run.

Install PrPro

Immediately update to the latest version before launching

Launch and test

This Bug has been around from PrPro CS3, and has affected users with CS4 and CS5. As CS5.5 has not had any updates yet, only time will tell if it has been eliminated, or will bite again. The vast majority of users never see it, and the program updates perfectly, but for some, it happens, though seldom with ALL updates - just some. This random nature has proved an issue, when Adobe has tried to correct the issue.

I was hoping to "hide" this in here, as it seems that about 5% of PrPro updates trigger this Bug. There is no Tips & Tricks section in the PrPro forum, and with the HTML link to the Adobe Cleaner Tool, I did not want that to be lost. About the 100th time that I typed out the steps, I got lazy, and hoped that being able to just link to here would save me that typing.

Most of the articles here are good for both PrE, or PrPro, and for mine, I try to distinguish between any program-specific aspects, so that users of either program could use them.

If you feel that this is inappropriate, I will work out some other repository, as this IS PrPro-specific - have not seen this Bug in any version of PrE.

Thanks you for your post. This could be the issue I'm dealing with upgrading from a stable CS4 to a trainwreck with CS5.5. I've uninstalled and re-installed CS5.5 used the Adobe cleaner tool several times. I've called Adobe tech support and followed detailed instuctions several times. My how I've tried to get it right. But while my desktop is fairly stable, my laptop is nothing but a time wasting struggle to find a working solution.

I can't update because PPCS5.5 crashes as it launches, before I can update. What is Adobe doing about this?

Now, historically, the Revert to Trial Bug has only shown up, after an update to PrPro. It has been occurring, though randomly and only for a few, since CS 3, through CS 5. PrPro CS 5.5 has not yet been updated (Aug 2011), so I would imagine that something else is happening, if you have lost the HD Presets for Sequences and Export. Also, the trial for CS 5.5 differs from earlier versions, in that MPEG is not omitted, like before. The trial of CS 5.5 is fully functional, so if it were to revert to trial, nothing like this should happen. Because of those two factors, I would guess that something else is happening with your CS 5.5.

Hi there, I have tried to do as you have said, but after the first clean I can still see a few Adobe 5.0 App's in my App's folder. After rebooting twice I still can't get Adobe Cleaner Tool to see them in order to do another clean. Just comes up with a blank screen with nothing to select.

FYI Bill, I had no success with the Adobe cleaner tool. It is not good at cleaning up much of anything. It is a joke. Adobe's tech support has some additional procedures that might help but they did not fix my problem when I updated from CS4 to CS5.5. Matrox tech support had a solution that worked but in volved editing the registry. My strongly advise you to format your drive or buy a new drive and start from a clean build. If this is not possible, I've documented the long and conveluted procedures to possibly fix your problem, or not in on other strings in Adobe forum and in Creative Cow Adobe Premiere forum.

It was not the Matrox drivers that caused the problem. It was the update from CS4 to CS5.5. Many others had similar problems. Without the Matrox drivers the software had serious issues. Matrox tech support was way more capable than Adobe’s and they were able to provide a solution.

Oh I do agree that updates to PrPro from CS 3 through CS 5, did have a problem with the Revert to Trial Bug. It hit enough people to be very annoying. PrPro CS 5.5 changed the design of the Trial version, so if there is a Revert to Trial Bug in its updates, the symptoms would be very, very different.

Going back to CS 3 and CS 4, there was an Adobe CleanScript for each version released, though the one for CS 4 seemed to work perfectly in CS 3, when the Revert to Trial Bug hit. Now that the name of the script has been changed, and Adobe is up to CS 5.5, I wonder if something major was changed in that script, that has caused you, and the other poster, a problem. Once, it was 100% effective, so long as one did Reboot between running the CleanScript multiple times. That Reboot was very important.

Sorry that you are not getting those 100% results, as with previous versions of the script.

You have no reason to be sorry but I would like to have a few word with the Adobe developers that created the nightmare.

DOCUMENT the procedures! TRAIN tech support! Who knew about using several reboots? Why was it not documented. You caused a huge amount a frustration! Before I updated I researched procedures even asked Adobe on the phone and at NAB. I should have listened to a few people in the forums that recommended a clean install on a new drive.
